General Motors has issued four more recalls that covers over 500,000 cars in the United States. One of the recalls covers MY2010-2014 Camaro over an ignition switch issue similar to the one that resulted to a recall of 2.6 million vehicles. In Camaro’s case, GM remarked that the switch complied with all engineering specifications and is unrelated to the ignition system employed in the cars included in the previous recall.

The Camaro recall affects 464,712 units in the US and another 46,816 in foreign markets like Canada and Mexico. According to GM, a driver’s knee can bump the key fob, knocking the switch out of the “run” position and cutting power to the engine. GM said it was aware of three crashes and four minor injuries tied to the issue.

According to the carmaker, the defect was discovered during internal testing this year. To resolve the issues, GM will make the key and fob separately from each other. The current design hides the key within the fob, which can be released with just press of a button.

Jeff Boyer, GM vice president of global safety, said in a statement that the quick discovery and the company’s action of the defect is an example of the new norm for product safety at the carmaker.

The other three recalls cover: 21,567 MY2012 Chevrolet Sonic subcompacts due to a transmission turbine shaft that can fracture in vehicles fitted with six-speed automatic transmission and the 1.8-liter four-cylinder engine; 14,765 MY2014 Buick LaCrosse sedan over a wiring splice in the driver’s door that can corrode and break, thereby cutting power to the windows, sunroof and door chime under certain conditions; and 8,789 units of the MY2004-2011 Saab 9-3 convertible over a cable in the driver’s seatbelt tensioning system that can break.

GM has now issued 38 recalls so far this year covering a total of 16.5 million vehicles, including 14.4 million vehicles sold in the US.
